The Injection Bar is a high strength-impact resistant heavy wall steel tubing conforming to ASTM A519 which is continuously threaded over it's 10' length with a heavy duty left hand thread/deformation pattern. The steel tubing provides maximum flow with minimum resistance during high pressure flushing and grouting operations. The thread form (similar for all diameters) is a unique Williams feature that provides a lower thread pitch angle to provide easier coupling disengagement without “locking up”, than conventional rope threads during drilling operations. This thread form provides more surface area and thread/deformations per unit length for superior bond capabilities over that of competitive drill steel thread forms. The bar's thread/deformation pattern has also shown to exceed the bond characteristics of ASTM A615 reinforcing steel. The lower thread angle allows the installed anchor to be torque-tensioned for fast tie back installations. The Geo-Drill Injection Anchor system is available with enhanced corrosion protection with hot-dip galvanized/epoxy coated bars and components. Installation adapters for the Geo-Drill Injection Anchors are available for all drill rigs.
